A report of 26 cases of ovarian lesions as seen in a Tertiary Institution in North-East Nigeria

varian cancer is a lethal disease. Globally, it claims 125,000 lives per year. Non-neoplastic lesions of the ovary frequently mimic ovarian neoplasms; many occur in the reproductive years and may be associated with infertility. The clinical diagnosis of ovarian cancers is still problematic when compared with that of the cervix owing to the fact that the ovary is less accessible and there has been no universally accepted screening protocol. : To study the pattern and age distribution of non-neoplastic and neoplastic lesions of the ovary in a tertiary institution in North – east Nigeria and compare it with other centers. : It was a retrospective retrieval of oopherectomy specimens seen over a 1 year period with review of their histopathologic characteristics. : A total of 26 oophorectomy specimens were received within the study st st period (1 January 2012 to 31 December 2012). There were 11(42.3%) nonneoplastic conditions and 15(57.7%) neoplastic conditions of which 8 (30.8%) were benign and 7 (26.9%) malignant tumours .The age range of non-neoplastic conditions was 20 to 49 years. Corpus luteum cyst was the most common lesion 4 (15.4%) and a case of ovarian ectopic gestation was observed. Neoplastic lesions were predominantly observed in fourth, third and second decades of life with age range of 17 years to 72 years. Papillary serous Cystadenocarcinoma was the most common malignant tumour, 5(19.2%). : The most common non-neoplastic ovarian lesion was Corpus luteum cyst and the most common benign and malignant ovarian neoplasm was papillary serous Cystadenoma and papillary serous Cystadenocarcima respectively. A further review may be needed in the future to compare epidemiologic trends in the environment
